TO ALL HOM 11' MAY coaches:

Be it known that I, Gimmes E. Mooma'of Elizabethpert, in the county of Union, and State of New Jersey, have invented a new and useful Improvementin' F-luid Meters andl do'hereby declare that the following is a fall, ciear,,and e'xact description thereof, which will enable others skilled in the art to inal-ze and use the same, reference being had to the'accompauyin'g drawing, forming part oi this specification, in which- Figure 1 is afront view of chamber and dial of the register. 7 5

Figure 2 is a transverse vertical section of the interior mechanism of themeter.

Similar letters of reference indicate like parts. v The object of this invention is to weigh and measure any fluid automatically, by means of the grarity of the same, as will hereinafter be fully set forth:

In the accompanying plate of drawings, the case or chamber containing the mechanism is shown at 1, and Y is a cubical box, of sheet metal, into which the meterprojxer slides with easy contact. This chamber is provided with a lid, B, and padlock or other lock, as shown.

It is further provided with a side door, which is, in practice, provided with a lock,'to secure the dials from inspection by any'bnt the person properly authorized to dose.

The dials are marked or otherwise aflixed to the plate 0', attached to or forming part of the frameot the mechanism, as shown, and their connection with the meter-pan will hereinafterbe set forth.

The pipe D, bearing afunnel, E, discharges iato'the ineter-pauK, which latter swings downward uponany suitable hinge-device, as shown at a, which are gudgeons,'having bearings in the side-plates H, forming part of the frame of the meter. 1 4 v I From the bar of the meter extends an arm, I, hearing at its end a weight, J, sufficient to nearly balance registered.

the quantity of fluidwhich the pan will hold.

Additional weights 5 are to be set on with a. nnt,'c, when the particular specific gravity of I the fluid is vto be determined.

A cock, d, in the lower end of the pipe, serves to shut off the fluid from the pan, when the latter swings -down to discharge the fluid therein contained, and to accomplish this automatically, the cookie connected with the arm I byla lever, F, which is formedwith at; eye, g, which latter slides along in the arm I, when the latter rises or lowers with the movement ofthe meter-pan.

One ofthe gudgeons, a, bears an'arm, It, to which is pivoted a ratchet-pawl, i, and this pa'wlmovs forward a ratchet-wheel, 7:, at every downward'movement of the meter-pan. The shaft of this ratchet-wheel bears a pointer, j, which, asit revolves, enters upon a graduated dial, G, the number of times the meter-pan has been filled. The pointers of the other dials are shown in red, and their shafts are, in practice, connected with the shaft of theratchet-wheel byany suitable train of wheel-work, so that one thousand. or more gallons may be Thc operation of this meter is as i'ollows: The funnel is placed under the stream of fluid, andthe same passes downward into the meter-pan, and fills it, the ,cer-tnin'point at which the weight of-the fluid will counterbhlance the weightson the arm I, when the pan will swing down, as shown in red outlines, and discharge the flnid npon the bottom of the chamber, and in so swinging down, the cock (I is closed by the action of its arm,

as before described, this shutting ofl' the'flow of fluid until the pan rises again'to its horizontal position.

l This invention is more particularly designed to meet the wants of the Internal'Revenue Departmeutof the United States, which department have advertised for automatic spirit-meters which will both weigh and measure I spiritspnnd register the same.

'Having thus described my invention, Iclaim as new, and desire to secure by Letters Patent The combination of the hiiigedmeter-pan' K, arm I, weight J, cock at, pawl z, ratchet-wheel k, and any suitable registering-dials, all constructed and operated substantially as shown and described, and for the purpose'set forth. v

The above specification of my invention signed by me, this 5th day of. March,186$.
